[0004] The oyster cage in the above patent document is fixedly connected between the cage frame and the floating main body, which makes it inconvenient to adjust the depth of the oyster cage in the water after being placed, affecting the light and oxygen needs of oysters. Therefore, an oyster breeding cage lifting device suitable for tidal variation is proposed. UTILITY MODEL CONTENTS

[0005] To solve the above problems, an oyster breeding cage lifting device suitable for tidal variation is provided, which rotates the wire roller to pull the flexible wire, so that the flexible wire passes through the outside of the first wire reel and the second wire reel in turn, and one end of the flexible wire pulls the second fixed frame to move the breeding net cage longitudinally. At the same time, the breeding net cage moves longitudinally along the outside of the limiting rod through the limiting piece, avoiding deviation of the breeding net cage during longitudinal movement. The breeding net cage can be stably lifted longitudinally. The problem of inconvenient depth adjustment of the breeding cage is solved.

[0006] To solve the prior art problems, the application provides a oyster culture cage lifting device suitable for tidal changes, which comprises a floating box, a culture net cage arranged on the bottom of the floating box and capable of moving longitudinally, a lifting mechanism arranged on the bottom of the floating box and used for driving the culture net cage to move longitudinally, and a limiting rod arranged longitudinally on both sides of the floating box and used for limiting the moving path of the culture net cage.

DETAILED DESCRIPTION

[0030] In order to further understand the characteristics, technical means and specific purposes and functions achieved by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments

[0031] Referring to Figures 1-9 The figure marks are: 1, buoyancy tank; 11, air bag; 12, counterweight; 13, air pump; 14, air pipe; 15, control valve; 18, limiting rod; 19, counterweight ball; 2, culture net cage; 21, net cage cover; 22, fixed seat; 23, plummet ball; 3, limiting frame; 32, flexible piece; 33, anchoring device; 34, mounting hole; 4, lifting mechanism; 40, first fixed frame; 41, servo motor; 42, winding roller; 43, first winding wheel; 44, flexible winding; 5, second fixed frame; 51, second winding wheel; 6, limiting piece.

[0032] The top center of the culture net cage 2 is provided with a second fixed frame 5, and the second fixed frame 5 is rotatably provided with a second winding wheel 51 inside;

[0033] The top end of the second fixed frame 5 is fixed with a flexible winding 44, and the flexible winding 44 is wound from the outside of the first winding wheel 43 and the outside of the second winding wheel 51 in turn, and the end of the flexible winding 44 away from the second fixed frame 5 is wound on the winding roller 42;

[0034] The two sides of the culture net cage 2 are symmetrically provided with limiting pieces 6 that can slide with the limiting rods 18.

[0035] The first fixed frame 40 is provided with a servo motor 41 for driving the winding roller 42 to rotate, wherein one end of the winding roller 42 is fixedly connected with the output end of the servo motor 41. When adjusting the depth of the culture net cage 2, the servo motor 41 is started to drive the winding roller 42 to rotate. Specifically, when the servo motor 41 drives the winding roller 42 to rotate clockwise, the winding roller 42 will perform the operation of paying out the flexible winding line 44. At this time, the second winding roller 51 at the bottom of the flexible winding line 44 moves downward under the action of gravity and drives the culture net cage 2 arranged at the bottom of the second fixed frame 5 to move downward. Conversely, when the servo motor 41 drives the winding roller 42 to rotate counterclockwise, the flexible winding line 44 will be wound outside the winding roller 42, causing the length of the flexible winding line 44 to become shorter. At this time, the flexible winding line 44 drives the culture net cage 2 to move upward through the transmission of the second winding roller 51 and the second fixed frame 5. Thus, the depth of the culture net cage 2 in the water is adjusted, avoiding that the culture net cage is put too deep or too shallow to affect the demand of oysters for light and oxygen.

[0036] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the inner part of the floating box 1 is provided with an air bag 11, one end of the floating box 1 is fixedly provided with an air pump 13, the output end of the air pump 13 is provided with an air pipe 14, and the output end of the air pipe 14 is fixed to the air bag 11 and can extend into the air bag 11.

[0037] In order to enable the culture cage to stably float on the water surface, the air pump 13 is fixedly installed at one end of the floating box 1, and the output end of the air pump 13 is connected with the air bag 11 in the floating box 1 through the air pipe 14. At the same time, the air pump 13 is allowed to inflate and deflate the air bag 11 through the air pipe 14. When the air pump 13 is started and inflates the air bag 11 through the air pipe 14, the air bag 11 will gradually expand outward, resulting in an increase in volume and thus an increase in the buoyancy provided by the air bag 11. The process of increasing the buoyancy of the air bag 11 enables the floating box 1 and the culture net cage 2 carried thereby to stably float on the water surface. Conversely, when it is necessary to reduce the buoyancy of the air bag 11, the air pump 13 can deflate the air in the air bag 11 through the air pipe 14. This operation causes the air pressure in the air bag 11 to decrease, and the volume to correspondingly decrease, so that the buoyancy of the air bag 11 decreases. Thus, the carrying capacity of the air bag 11 can be adjusted according to the actual weight of the culture net cage 2, so as to ensure that the entire culture cage can maintain a stable floating state.

[0038] Referring to Figure 3 and Figure 4 , the air pipe 14 is provided with a control valve 15 for controlling the opening or closing of the air pipe 14.

[0039] A control valve 15 is arranged outside the air pipe 14. When the air pump 13 inflates or deflates the air bag 11 to a set value, the control valve 15 can close the air pipe 14 to prevent air from continuously entering or escaping from the air bag 11.

[0040] Referring to Figure 1 , Figure 2 and Figure 7 , the bottom end of the limiting rod 18 is provided with a counterweight ball 19, and the bottom of the limiting rod 18 is provided with a limiting frame 3 for positioning, and the limiting frame 3 is located at the top of the counterweight ball 19; both ends of the limiting frame 3 are provided with mounting holes 34 that can be adapted to the limiting rod 18.

[0041] To ensure the stability between the limiting rods 18, the limiting frame 3 is arranged at the bottom of the limiting rod 18, and the mounting holes 34 that can be mounted on the limiting rod 18 are arranged at both ends of the limiting frame 3. The distance between the limiting rods 18 is effectively avoided to change. The distance between the limiting rods 18 is avoided to change to cause the aquaculture net cage 2 to be unable to move longitudinally.

[0042] Referring to Figure 7 , the center of the bottom of the limiting frame 3 is provided with a flexible member 32, and the bottom end of the flexible member 32 is fixed with an anchoring device 33 for positioning the aquaculture cage.

[0043] To prevent the aquaculture cage from moving with the water flow, the flexible member 32 is arranged at the center of the bottom of the limiting frame 3, and the anchoring device 33 is arranged at the bottom end of the flexible member 32. When the water flow pushes the floating box 1, the floating box 1 is linked through the limiting rod 18 and the limiting frame 3. Then, the limiting frame 3 drives the anchoring device 33 to move through the transmission of the flexible member 32. In the process of moving the anchoring device 33, the anchoring device 33 will gradually sink into the riverbed, effectively avoiding the risk of the aquaculture cage being washed away by the water flow, and ensuring the stability and safety of the aquaculture system.

[0044] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the end of the floating box 1 away from the air pump 13 is provided with a counterweight 12, and the counterweight 12 is used to ensure that the floating box 1 remains in a horizontal state.

[0045] To ensure that the floating box 1 can always remain in a horizontal state, the counterweight 12 is arranged at one end of the floating box 1, so that the counterweight 12 can balance with the air pump 13. The floating box 1 is effectively ensured to always be in a horizontal floating state.

[0046] Referring to Figure 3 , Figure 5 and Figure 6As shown in the drawings, the fixed seat 22 is fixed at the center of the bottom of the breeding net cage 2, and the bottom of the fixed seat 22 is provided with a ball 23 for stabilizing the breeding net cage 2.

[0047] In order to ensure that the breeding net cage 2 can be kept stable in water, the fixed seat 22 is arranged at the center of the bottom of the breeding net cage 2, and the ball 23 is arranged at the bottom of the fixed seat 22, so that the breeding net cage 2 is kept stable under the downward traction of the ball 23, thereby effectively reducing the swing amplitude of the breeding net cage 2 caused by tides and water flow, and improving the stability of the breeding net cage 2.

[0048] Referring to Figure 5 and Figure 6 As shown in the drawings, one end of the breeding net cage 2 is provided with a net cage cover 21 which can be opened.

[0049] By arranging the net cage cover 21 at one end of the breeding net cage 2, when the aquatic seedlings are put into the breeding net cage 2, the net cage cover 21 can close one end of the breeding net cage 2, effectively avoiding the escape of the aquatic seedlings from the inside of the breeding net cage 2, thereby avoiding economic losses.
